Garages in Yorkshire to help get car IVA ready

[Wain]

I have Wilwood calipers on the front and sierra on the back. Can never get enough efficiency from the handbrake and this time i took it for a retest, it didnt get tested as the inspector thought it was 'binding' so didnt try testing it, nor did he do a full balance test as he didnt test the back wheels.
If i warm the engine from cold i can pass the emissions but when i drive it there i always fail the emissions, also when it gets warm it starts to idle at 2000 revs.
Constantly tweeking it but still not road legal hence looking to get it in a garage who can get the brakes set right and take a look at the engine to get emissions down and figure out why it idles so high when its hot.
